A simple mod, only to change the speed at which technology is researched. All game speeds now have longer research times, nothing else is changed. Quick speed now uses Normal speed for tech rate, Normal uses Epic, Epic uses Marathon, and Marathon (previously at 300) is now set at 500.
you'll need winzip, winrar, or equivalent to extract it.
Extract it to the Beyond the Sword/Mods directory, or whatever version your using. Should work with Vanilla, Warlords, and BtS.
